Hosta plant named ‘Pineapple Punch’

ABSTRACT

A new and distinct  Hosta  plant named ‘Pineapple Punch’, characterized by narrow pointed leaves having creamy yellow margins, and a deep green center, that displays a arching habit, and light lavender flowers held above the foliage on thick gray-green scapes.

Botanical classification: Hosta sp. (Tratt.).

Variety denomination: ‘Pineapple Punch’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of Hosta,botanically known as Hosta hybrid (Tratt.), and hereinafter referred toas the cultivar ‘Pineapple Punch’.

The new plant was discovered by the inventor, Amy Bergeron as anon-induced, naturally occurring whole plant mutation of Hosta‘Pineapple Upsidedown Cake’ (not patented) in a greenhouse at a nurseryin Zeeland, Mich., USA. Asexual propagation of the plant as the samenursery by tissue culture and division has shown that the unique anddistinct characteristics of this new plant are stable and reproduce trueto type in successive generations.

SUMMARY OF THE INVENTION

Hosta ‘Pineapple Punch’ is unique from its parent sport, Hosta‘Pineapple Upsidedown Cake’ (not patented) and all other hosta cultivarsknown to the inventor, in several traits. Hosta ‘Pineapple UpsidedownCake’ is a sport of Hosta ‘Pineapple Poll’ (not patented), a hybrid ofH. lancifolia×H. sieboldiana made by Eric Smith. Hosta ‘Pineapple Poll’is a solid green-leafed hosta with long pointed leaves, heavy substanceand a coarse wave or piecrust-like edge. ‘Pineapple Upsidedown Cake’ isthe same leaf form, smaller in size, with a light yellow to cream centerand dark green margin. ‘Pineapple Punch’ is a reverse-patternvariegation of ‘Pineapple Upsidedown Cake’ with the light yellow tocream color on the leaf margin and dark green center. All three plantshave similar growth and flowering habits except that ‘PineappleUpsidedown Cake’ is a slower grower and smaller mature size.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on The RoyalHorticultural Society Colour Chart (2001 edition) except where commondictionary terms are used. The new plant, Hosta ‘Pineapple Punch’, hasnot been observed under all possible environments. The phenotype mayvary slightly with different environmental conditions, such astemperature, light, fertility and moisture, but without any change inthe genotype. The following observations and size descriptions are of athree-year old plant in a one gallon container grown in Zeeland, Mich.,USA under 50% supplemental shade, day temperatures of 18 to 32 degreesC., and night temperatures of 14 to 22 degrees C.

-   Botanical classification: Hosta sp. cultivar ‘Pineapple Punch’.-   Parentage: Naturally occurring whole plant mutation of Hosta    ‘Pineapple Upsidedown Cake’ (not patented).-   Propagation: Method by tissue culture and division, Time to initiate    roots from both division and tissue culture about three weeks.-   Rooting habit: Normal, fleshy, to 3 mm thick, lightly branching.-   Plant habit: Herbaceous, moderately loose rhizomatous perennial,    symmetrical, radical glabrous above and glaucous underneath leaves    upright and erect through flowering period, (14 to 16 leaves per    division), more horizontal late in the season and in maturity.    -   -   Crop time.—Under normal summer greenhouse growing conditions            about 16 weeks to finish in a one-liter container. Plant            vigor is very good.        -   Plant size.—Foliage at flowering is 30 to 35 cm tall and 40            to 50 cm wide.-   Foliage description:    -   -   Shape and size.—Ovate to broadly ovate leaf blades have an            acute apex and cordate base. The leaf blades are 18 to 20 cm            long and 5 to 7 cm wide. The leaf blade margin is entire and            the cream to light yellow variegation pattern on the edge            varies in different regions of the leaf from 3 to 6 mm wide.            Petioles are 14 to 16 cm long and 5 mm wide in the center            broadening slightly at the plant base (ground) and tapering            at the leaf blade.        -   Venation.—Parallel, same color as surrounding leaf surface            on the top and slightly whiter on the bottom.        -   Leaf blade color.—Adaxial (upper) surface: early season a            deep green closest to RHS 137 C in the center, RHS 154 D on            the margin. Later in the growing season the center is            greener than RHS 127 A and bluer than RHS N138 A; the margin            lightens to RHS 11 D. Abaxial (lower) surface: early in the            season is RHS N 138 D on the center and RHS 144 C on the            margin. Later in the season the lower surface is RHS N 138 C            in the center and RHS 11 D on the margin.

There is no clear intermediate color band on either surface, but rathera melded yellow-green RHS 154 B on older leaves with an occasional greenline the same color as the top or bottom center protruding into themargin.

Petioles colors are the same as the respective leaf colors with themargins being more greenish-yellow in the shadier portions and morecreamy-colored in higher light levels. The basal one third of thepetiole has a gradient of reddish purple stipling RHS 61 A increasing inquantity (density) closer to the ground.

-   Flower description:    -   -   Buds.—Torpedo-shaped, flared at apex; two days prior to            opening the buds are between RHS 75 C and RHS 75 D with            veins of RHS 70 B; and RHS 85 A, 6 to 7 cm long, up to 1.5            cm wide.        -   Peduncle.—7 to 9 mm in diameter, erect to 95 cm; closest to            RHS N 138 C with some RHS 61 A stipling near base.        -   Pedicel.—1 to 1.2 cm long, 3 mm in diameter, curved slightly            downward, RHS N 80 D.        -   Flowers.—30 to 36 per scape, 4 to 6 scapes per plant;            funnelform; 5 to 7 cm wide and 6 to 8 cm long, (distal            flowers being smaller) subtended by a simple, entire,            narrowly-acute, sessile bract with base wrapped around            scape, up to 2 cm long and 7 to 10 mm wide with a border on            both surfaces lighter than RHS 59 D and center on both            surfaces closest to RHS 143 D; flowers persist for a normal            period, up to two days on or off the plant, and the scapes            remain effective from early to late August. No fragrance has            been detected.        -   Tepal.—Six, simple, entire, fused at the base, oblong to            elliptic, with slightly-recurved acute apex, approximately 5            to 6 cm long and 1.5 cm wide, arranged in two layers of            three, the inner three with clear 1 to 2 mm margin toward            the apex, main adaxial (inner) color in center of tepals is            Red purple RHS 25 B and three prominent violet stripes of            RHS 84 B. The back of the tepals is between RHS 76 B and 76            C with less obvious stripes about RHS 71 C.        -   Gynoecium.—Single, style — 7 to 8 cm long, 2 mm diameter,            near white, curled upward at distal end; Stigma — entire,            white, up to 3 mm diameter.        -   Androecium.—Filaments — six, white, approximately 1 mm in            diameter and up to 5 cm long; curved at tips.        -   Anthers.—5 to 6 mm long, 2 mm wide, about RHS N 79 A around            margin of abaxial side, white in center, pollen is            yellow-orange RHS 17 B.-   Fruit: Tri-valve, longitudinally dehiscent capsule, about 2.5 to 3    cm long and 5 mm diameter, when mature is a combination of RHS 164C,    RHS 165B and some regions of RHS N167 B; as developing RHS.-   Seeds: flat winged samara with embryo at one end, 10 to 24 per pod,    approximately 10 mm long and 3 mm wide.-   Disease resistance: The plant grows best with plenty of moisture but    is able to tolerate some drought especially once established.    Hardiness to at least USDA zone 3, and other disease resistance is    typical of other hostas.
